Arduino lilypad to control LEDs

Hello, I'm looking for someone that can help with the electrical engineering to connect an Arduino Lilypad to two separate strings of RBG programmable LED string lights, all powered by a battery. The Arduino would need to control the individual LED light strings so that as they were moving, a pattern would appear to an observer, like a smiley face, for example. I would also need software written (could be coded by someone else if needed) to allow a user to upload their own LED patterns onto the Arduino via the micro USB connection. This is a basic description of the project, if you are interested I can provide further detail. Thank you! Brian Baugh
